针对冬水田影响水稻生长的土壤障碍因子,研究了不同土壤改良剂对冬水田水稻产量、养分吸收和土壤还原性物质总量的影响。两年试验结果表明：所有处理中鸡粪和硅钙肥增产效果较好,2011年较对照分别增产11．3%和10．7%,2012年较对照分别增产9．4%和13．0%；在还原性物质总量上,鸡粪处理较对照增加5．7%,在一定程度上提高了土壤有害物质增加的风险,不宜长期在冬水田中施用,而硅钙肥处理则比对照降低19．6%。石灰的效果不稳定,可能与两年遇到的极端天气(第一年严重干旱,第二年涝灾)有关,其效果还需要继续验证；锌肥的效果较差。因此,对长期淹水、地势较低的冬水田来说,硅钙肥是比较理想的土壤改良剂,施用后能保证水稻健壮生长和获得高产。

In order to eliminate the adverse soil factors affecting rice growth in the all-time waterlogged paddy field in a two-year period, effects of different soil amendments on rice yields, nutrient uptake and soil reductants were investigated. The results showed that among all the treatments, chicken manure and silicon-calcium fertilizer produced much higher rice yields, in-creased by 11. 3% and 10. 7% in 2011 and 9. 4% and 13. 0% in 2012 than the control, respectively. Chicken manure, how-ever, had 5. 7% higher contents of soil total reductants than the control, and could bring a potential risk of harmful soil reduc-tants if applied continuously. Just on the opposite, silicon-calcium fertilizer effectively reduced soil reductants by 19. 6% than the control. The response of rice yield to added lime appeared unstable in the two years, most likely due to the extreme weather encountered ( severe drought in the first year and severe flooding in the second year) . Thus, its effect on rice in this region needs further field experiments to substantiate. Zinc fertilizer behaved poor and unstable effect in this experiment. Therefore, silicon-calcium fertilizer could be considered as an ideal soil amendment to use in the all-time waterlogged paddy field for healthier growth and better yield of rice.
